以下、図面を参照しながら本発明を更に説明する。   The present invention will be further described below with reference to the drawings.

（第１実施形態）
図１と図２に示すように、本発明に係る振動モータ１００は、ハウジング１と、ハウジング１に収納されるステータ２、振動子３と、振動子３を弾性的に支持する弾性支持部材４と、を備える。 (First embodiment)
As shown in FIGS. 1 and 2, a vibration motor 100 according to the present invention includes a housing 1, a stator 2 and a vibrator 3 housed in the housing 1, and an elastic support member 4 that elastically supports the vibrator 3. And comprising.

ハウジング１は上部ハウジング１１と上部ハウジング１１と配合して収容空間を形成する下部ハウジング１２を備える。上部ハウジング１１は、天壁１１１と、天壁１１１から折り曲げて延在する側壁１１２とを備える。下部ハウジング１２は天壁１１１に対応する底壁１２１及び底壁１２１の縁部から天壁１１１方向へ折り曲げて延在するフランジング１２２を備える。フランジング１２２は、側壁１１２の内面に当接していることで、ハウジング１のパッケージを実現する。   The housing 1 includes an upper housing 11 and a lower housing 12 that is blended with the upper housing 11 to form an accommodation space. The upper housing 11 includes a top wall 111 and side walls 112 that are bent from the top wall 111 and extend. The lower housing 12 includes a bottom wall 121 corresponding to the top wall 111 and a flanging 122 extending from the edge of the bottom wall 121 by bending toward the top wall 111. The flanging 122 is in contact with the inner surface of the side wall 112, thereby realizing a package of the housing 1.

ステータ２がハウジング１に固定され、弾性支持部材４の一端が振動子３に接続され、他端がハウジング１の側壁１１２に接続される。   The stator 2 is fixed to the housing 1, one end of the elastic support member 4 is connected to the vibrator 3, and the other end is connected to the side wall 112 of the housing 1.

ステータ２は、具体的には、ハウジング１に配置されたコイル２１と、コイル２１に対応するコア２２とを備える。振動子３は、コイル２１とコア２２とを取り囲んでコイル２１とコア２２とから間隔をあけて配置されたリング状の永久磁石３１を備える。コイル２１は、通電中に磁界でローレンツ力を受けて振動子３を軸方向に沿って振動させるように駆動する。具体的には、本実施形態において、コイル２１は、天壁１１１に配置された第１コイル２１１と、底壁１２１に配置された第２コイル２１２とを備える。第１コイル２１１及び第２コイル２１２はコア２２の両端からコア２２に外嵌されたフラットコイルである。通電中には、コイル２１とコア２２との間に磁界が形成され、振動子３の永久磁石３１との間に軸方向の駆動力が形成されて振動子３の振動を駆動する。   Specifically, the stator 2 includes a coil 21 disposed in the housing 1 and a core 22 corresponding to the coil 21. The vibrator 3 includes a ring-shaped permanent magnet 31 that surrounds the coil 21 and the core 22 and is spaced from the coil 21 and the core 22. The coil 21 receives a Lorentz force with a magnetic field during energization and drives the vibrator 3 to vibrate along the axial direction. Specifically, in the present embodiment, the coil 21 includes a first coil 211 disposed on the top wall 111 and a second coil 212 disposed on the bottom wall 121. The first coil 211 and the second coil 212 are flat coils that are externally fitted to the core 22 from both ends of the core 22. During energization, a magnetic field is formed between the coil 21 and the core 22, and an axial driving force is formed between the permanent magnet 31 of the vibrator 3 to drive the vibration of the vibrator 3.

さらに、第１コイル２１１と第２コイル２１２との間にさらに仕切り板２３が設置される。仕切り板２３の下面が第２コイル２１２の上面に当接し、仕切り板２３の上面が第１コイル２１１の下面に当接する。第１コイル２１１と第２コイル２１２と仕切り板２３の外径はいずれも同じである。仕切り板２３はリング状の構造であり、二つのボイスコイルを分離して、位置決めを補助することに用いられる。仕切り板２３は磁性材料で製造されてもよく、非磁性材料で製造されてもよい。好ましくは、仕切り板２３は磁性材料で製造され、このようにして、位置決めを補助することができるだけではなく、能動的な磁気伝導の役割を果たすことができ、同一方向の磁界が同時に二つのボイスコイルを通過することを防止する。   Further, a partition plate 23 is further installed between the first coil 211 and the second coil 212. The lower surface of the partition plate 23 contacts the upper surface of the second coil 212, and the upper surface of the partition plate 23 contacts the lower surface of the first coil 211. The outer diameters of the first coil 211, the second coil 212, and the partition plate 23 are the same. The partition plate 23 has a ring-like structure, and is used to assist positioning by separating the two voice coils. The partition plate 23 may be made of a magnetic material or a non-magnetic material. Preferably, the partition plate 23 is made of a magnetic material, and thus can not only assist in positioning, but can also play an active magnetic conduction role, and a magnetic field in the same direction can simultaneously play two voices. Prevents passing through the coil.

振動子３はステータを取り囲むリング状の永久磁石３１と、永久磁石３１の天壁１１１に近寄る側に設置される第１極コア３２と永久磁石３１の底壁１２１に近寄る側に設置される第２極コア３３とを備える。そのうち、第１極コア３２は永久磁石３１の上面に貼り付けられ、第２極コア３３は永久磁石３１の下面に貼り付けられ、且つ第２極コア３３の内径は永久磁石３１と同じであり、外径が永久磁石３１より小さく、このようにして、弾性支持部材４の変形空間を提供することに有利である。   The vibrator 3 is a ring-shaped permanent magnet 31 that surrounds the stator, a first pole core 32 that is installed on the side of the permanent magnet 31 that is closer to the top wall 111, and a first that is installed on the side of the permanent magnet 31 that is closer to the bottom wall 121. A two-pole core 33. Among them, the first pole core 32 is attached to the upper surface of the permanent magnet 31, the second pole core 33 is attached to the lower surface of the permanent magnet 31, and the inner diameter of the second pole core 33 is the same as that of the permanent magnet 31. The outer diameter is smaller than that of the permanent magnet 31, and thus it is advantageous to provide a deformation space for the elastic support member 4.

弾性支持部材４はリング状のリーフスプリング４１及びリーフスプリング４１の両側に設置された第１固定リング４２及び第２固定リング４３を備える。リーフスプリング４１はハウジング１に接続された外輪４１１と、振動子３に接続された内輪４１２と、外輪４１１と内輪４１２とを接続する接続輪４１３とを備える。第２極コア３３の一側は永久磁石３１の底部に当接し、他側はリーフスプリングの内輪４１２に接続される。第１固定リング４２及び第２固定リング４３はリーフスプリング４１の外輪４１１を挟持して固定する。第２固定リング４３は前記リーフスプリング４１の下面に設置され、且つハウジング１のフランジング１２２にオーバーラップされる。これにより弾性支持部材４と振動子３の固定を実現する。   The elastic support member 4 includes a ring-shaped leaf spring 41 and a first fixing ring 42 and a second fixing ring 43 installed on both sides of the leaf spring 41. The leaf spring 41 includes an outer ring 411 connected to the housing 1, an inner ring 412 connected to the vibrator 3, and a connection ring 413 that connects the outer ring 411 and the inner ring 412. One side of the second pole core 33 is in contact with the bottom of the permanent magnet 31 and the other side is connected to the inner ring 412 of the leaf spring. The first fixing ring 42 and the second fixing ring 43 sandwich and fix the outer ring 411 of the leaf spring 41. The second fixing ring 43 is installed on the lower surface of the leaf spring 41 and overlaps the flanging 122 of the housing 1. Thereby, the elastic support member 4 and the vibrator 3 are fixed.

さらに、振動モータは第２コイル２１２の電気的接続を実現するための可撓性回路基板５を備え、第２コイル２１２上のコイルリード線は可撓性回路基板５に電気的に接続され、さらに、ハウジング１の天壁１１１には天壁１１１を貫通する貫通孔１１１０が設置される。貫通孔１１１０は、第１コイル２１１が天壁１１１における正射影内に配置され、コイルリード線２１１１は、第１コイルの縁部から天壁１１１方向に垂直に延在して、且つ貫通孔を貫通して、ハウジング１の外部まで延在することで、第１コイル２１１と第２コイル２１２とのそれぞれ電気的接続を実現する。これによって異なるコイルリード線がハウジング内に巻きついた又は破損したことによって製品の信頼性に影響を与えることを避ける。貫通孔１１１０は第１ボイスコイル２１１が頂壁１１１における正投影内に設置されて空間を最大限に利用することができ、磁気回路空間を占有することを避けるので、製品の電磁特性がさらに保証される。   Further, the vibration motor includes a flexible circuit board 5 for realizing electrical connection of the second coil 212, and a coil lead wire on the second coil 212 is electrically connected to the flexible circuit board 5, Furthermore, a through hole 1110 that penetrates the top wall 111 is provided in the top wall 111 of the housing 1. In the through hole 1110, the first coil 211 is disposed in an orthogonal projection on the top wall 111, and the coil lead wire 2111 extends perpendicularly from the edge of the first coil in the direction of the top wall 111. By penetrating and extending to the outside of the housing 1, electrical connection between the first coil 211 and the second coil 212 is realized. This avoids affecting the reliability of the product due to different coil leads being wound or broken in the housing. The through-hole 1110 has the first voice coil 211 installed in the orthographic projection on the top wall 111 to make maximum use of the space and avoids occupying the magnetic circuit space, thus further guaranteeing the electromagnetic characteristics of the product. Is done.
